Specification forming part of Letters Patent No. 191,929, dated June12,1877 application filed October 9, 1876.

1o all whom it mag/concern:

Be it ,known that i. JOHN E. BUX'roN, of Owatonna, in the county ofSteel and State of Minnesota, have invented certain new and usefulImprovements in Grain -Binders, of which the following isaspecicationFigure l represents, in perspective, my

l grain-binding machine. Fig. 2 represents, in

perspective, the gear-ings that operate the wire-twisting wheel. Fig. 3represents the forked receiver `and block, upon which the binding-wireis clamped. Fig. et represents the gevel-compressor.

My invention relates to that class of grainbinding machines, in whichwire is used to bind the grain, `and is to be employed in connectionwith harvesters, in which the cut grain is received on an endless apron,and elevated by means of canvas or belts, or any suitable device, abovethe drivingwheel of the harvester, and comesjdo'wn on the oppo site sidein a continuous stream, and being an improvement upon the Letters Patentgranted to me June 20, 1876. Some ofthe parts fullv described in thatpatent, being used in this machine, need not be described in detail.

My invention consists in providing a harvester-binder with a revolvingreceptacle, operated intermittently to receive the eut grain and deliverit in gavels to the binding mech! anism; a shield hinged to the frame,to direct the gavel from the receiver to the binding mechanism; acompressor operated by intermittent gearing and a spring; a stationaryforked arm or receiver and block, in connection with a clamping-arm, toreceive and retain the binding-wire; a wire-twisting mechanism operatedby a segmentgear and a tension and take-up arrangement forthebinding-wire, all as will now be more fully de- I scribed.

In the drawing, A represents the frame of the machine, and B the maindriving-shaft. Gis arock-shaft, receiving its motion from the shaft Bthrough the medium of the cranks a and b and connecting-rod c. Drepresents a grainreceiver, having four wings to receive the coutinuousfalling grain and divide it into bundles. This receiver is attached to ashaft, d, that is automatically revolved one-quarter of a revolution ata time, and receives its motion from the rock-shaft() through the mediumof the crank b' androd e, operating a pawl,f, thatengages with aratchet-wheel, d', mounted upon one end of the shaft d, while at theother end vthere is a small wheel, g, having four notches upon itscircumference, in which the spring-hook g' engages, to retain thereceiver D in position while the grain is falling into it. E representsa shield, formed of a series ofbent wires attached to a rod, E', hingedat e' to the frame A above the receiver, to retain the grain while thereceiver is turned, and direct it to the compressing `and bindingmechanism.

The compressing mechanism is formed of two bentarms, F F, mounted upon ashaft, F', connected to the frame by suitable bearings. Upon oneextremity of the shaft F' there is a segment gearwheel i, operated bythe main shaft B through the crank h and connectingrod h'. Thesegment-wheel t' gears with a pinion, i', mounted upon oneend oftheshaft G, that carries the spring compressing-arm H. This arm is mountedupon a sleeve, H1,whichl is fitted loosely upon the shaft G, and isconnected with said shaft at one end by the coiled spring G', and at theother by a prolongation, H2, resting at certain times against a button,J, projecting from the shaft G, the arms F, F, and H forining a claspingand compressing device. for the bundle of grain. A slotted platform canbe used, as in my former patented machine, to support the grain in ahorizontal position on each side of the arm H, and wire-cutting nippersare also used; but the griping device to hold the wire next to thebundle while the ends are twisted together is different, Iand is asfollows:

To the frame is attached, in front ofthe twisting-wheel, a forkedwire-receiver, I, and a block, I', upon which the binding-wire isclamped at the right time by the clamping arm K, pivoted in bearings `ofthe frame A. This arm is retained in a vertical position by the coiledspring k, wound around the central portion of its stem, and the rearend. is bent at K', so as to be in the path of a bent arm, B', revolvingwith the shaft B, that brings, for a short interval of time, the arm Kin close contact with block I', and etfectually clamps the wire, whilethe ends are uuitedby the twistin g-wheelL. This wheel L is mounted upona shaft, l, rotating in suitable bearings attached to the frame A. Thisshaft carries a pinion, m, that meshes with a crownwheel, M, havingteeth only upon a portion of its circumference, and arranged so that acouple of teeth (more or less) will give the pinion and twisting-wheelone-half of a revolution, after having first received the former end ofthe wire, before receiving the opposite end. There is then a vacancybetween the teeth, to give time to the clamping-arm K to seize both endsof the Wire before the twistingwheel is revolved by the remaining teethupon the crown-wheel M. The first cog n is placed upon the end of thespring n attached to the crown-wheel, so that there will be no dangervof breakage or strain upon the gears if the cogs upon the crown-wheeland pinion should not come together in position to mesh.

The binding-wire is brought fromthe spool N around the'pulley o to acrescent wire-carrier, C', the upper extremity of which should beconstructed similarly to the one shown in my former patent. This carrieris connected to the rock-shaft C, and is operated once for eachrevolution of the main shaft B.

The spool N is placed upon ashaft,p, mounted upon a sliding carriage, P,that can move back and forth upon horizontal rods A. The carriageP isconnected by means of a yoke, g, and cord q1 passing over a pulley, q2,with a weight, Q, free to run up and down within a tube, R, said weightacting to take up any slack wire during the operation of binding. Uponthe shaft p, between one of its bearings and the nut r, there is arubber spring, s, to regulate the tension upon the wire of the spool,and upon the band passing around the bundle.

Tobind grain with this machine, motion is transmitted from the harvesterto the main driving-shaft B, the binding-wire having been passed fromthe spool N over the guide-pulleys, and the extremity of the arm cthrough one of the indentations of the twisting-wheel to the pinchers,as shown in my machine previously patented. The receiver D is placed inposition to receive the falling grain, with the end of the spring-hook gWithin one of the notches of the Wheel g. The machine is started, andthe grain, guided by the shield E, falls upon the binding-wire, and isretained by the compressor H and slotted platform, if

one is used. The shaft B, continuing to rotate, brings the compressor Fdown upon the bundle by revolving the segment wheel partly round, thelatter turning the pinion fi', and its shaft G allows the compressor Hto rise, and itsl sleeve extension H2 being released from the button Jupon the shaft, the spring G continues to press the arm H against thebundle of grain. The wire-carrier C vis then brought down, and continuesthe operation of encircling the bundle of grain with the Wire, its upperend overlapping the pinchers. The wire is then caught by them and thencut ready to be twisted, both ends of the wire having previously beenretained together next to the bundle, between the vibrating arm K andblock I'-. After the ends of the wire have been twisted together the armH is turned down'and the sheaf dropped upon the ground, the machinebringing a new bundle every quarter of a revolution of the main shaft.The above-described operations are repeated for every sheaf.

Having thus fully described my invention, what I claim is 1. Incombination with a grain-receiver, D, revolved periodically, and ashield hinged above it to guide the falling grain from the firstreceiver, D, to a second receiver, the compressor H and its sleeve H1,mounted loosely upon a shaft, G, to which it is connected by a spring,G', substantially as and for the purposes described.

2. In combination with a grain-receiver, D, shield E, compressor H, andwire-twisting wheel L, a forked wire-receiver, I, holding block Ilconnected rigidly to the frame and clamping-arm, substantially asdescribed.

3. In combination with the. twisting-wheel L and pinion m, the segmentcrown-Wheel M and spring-cog n, substantially as and for the purposesdescribed.

4. In a grain-binder, substantially as set forth, and combinedtherewith, the take-up Weight Q and carriage P for the binding wirespool, and the tension-spring s, all substantially as and for thepurposes set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

JOHN E. BUXTON.
